GMC Sierra 3500HD brings you at the extreme end of the work spectrum. Its bold exterior and mean power unit comes to do the most demanding tasks while also boasting premium materials and features – if you’re into that kind of stuff while at work. The standard engine provides 401hp and can be upgraded to a 445hp, 910lb-ft. 6.6-liter Duramax unit with an Allison transmission to tow and get out of the dangerous swamps and forest roads. Since it’s built to tow, the Sierra 3500HD brings an auto-locking rear differential, StabiliTrak system, Hitch Guidance, and trailering package. For more information at gmc dealers near me
